l MPROVEM ENT IN GRAIN-SEPARATRS.

Speciiication forming part of Letters Patent No. 209,435, dated October29, 1878; application filed July 31, 1878.

To all whom t may Conor m:

Be it known that we, CLAYTON MARIE VAN ORMAN and JAMES MADIsoNHAGENBAUGH, of Athens, in the county of Calhoun and State of Michigan,have invented a new and Iniproved Fanning-Mill, of which the followingis a specication:

In the accompanying drawing, Figure 1 represents a vertical section ofthe forward part of a fanningmill constructed according to ourinvention. Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

The obiect of our invention is to provide a so improved combination andarrangement of the screens, feed-board, and blast of a fanningmill as toeffect the thorough removal from grains of all impurities, and by theuse of only two screens.

A is the vibrating shoe of the fanningmill, and is suspended from theframe of the latter by a pivot, a, and side straps b, in the usualmanner. B is the chute leading the grain from the hopperto thefeed-board. C is a coarse screen placed in inclined grooves in the sidesof the shoe, in the usual place ot' the ordinary feed-board, to receivethe grain from the chute BA from the hopper. The screen C, beinginclined to the front of the shoe, removes all straw and other coarsesubstances from the wheat or other grain,the latterfalling throughthe-screen C before coming on the feed-board.

D is the feed-board,placed under the screen C in grooves allowing it tobe moved back and forward to adjust its position for conveying the grainto and letting it fall upon the forward upper end of the lower screen,E. The rear end of the feed-board D extends back under the chute B. Thelower screen or cockiescreen, E, is pivoted on opposite sides at itsfront end by screws or pins c, and its rear end bar is provided with apin, d, by which it is supported in one or other of a series. of holesin the lower part of a strap, e, secured with its upper end to the underside of the chute B. v

grain upon the screen to allow cockle and otherI seeds to be shakenthrough the screen by the motion of the mill. The said impurities fallon the inclined board F, and are discharged through the opening f. Thegood seeds of wheat or other grain fall off the rear end of thecockle-screen onto the inclined board Gr, and are discharged at g.-

H is a wind-chute iiXed in continuation with the fan-case, andconstituting the lower side of the blast-opening of the fan. The chute His so arranged that when the cockle-screen is in the position shown indotted lines the blast will be directed in an unbroken volume againstthe under side of the forward end of the feedboard, and, deflected fromthe same, will strike the wheat or grain as the latter falls from thefeed-board onto the lower screen and blow off from it all lightsubstances, such as chaff, oats, chess, v and other impurities, allowingonly heavier bodies, such as wheat, corn, rye, cockle, and grass-seed,&c., to fall upon the lower screen.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- The combination, in the shaking-shoe A, of thetop screen, C, the conveyer-board D, the adjustably-inclined screen, E,pivoted at its outer end, and the wind-board H, all relatively arrangedand operating substantially as and for the purpose specified.
